This document presents the requirements for a built-in service port to be used in vehicles intended to comply with Enhanced Evaporative Emissions Requirements. The primary function of the Service Port (Valve Assembly-Evaporative Emission Canister Purge Harness Service) is to provide non-destructive access to the evaporative emissions system to enable testing of the integrity of the system. The Service Port is used to introduce air pressure or fuel vapors into, or evacuates them out of, the system. This access may be used for the following evaluations: • Evaporative System Certifications Canister Loading and Purging • End-of-line Testing System Integrity • Service (e.g. OBD MIL on) Leak Location and Repair Verification • In-Use Compliance Testing Canister Loading and Purging • Inspection/Maintenance Testing System Integrity and Purge Check

This SAE Recommended Practice was developed primarily for gasoline-powered passenger car and truck applications to interface vapor recovery systems, but may be used in diesel applications, marine, industrial, and similar applications where a nozzle is required for filling. The zones cover nozzle spout access and handle clearance to a refilling port. In addition, this practice includes a design window for nozzle manufacturers to develop with.

This SAE Recommended Practice provides standard dimensions for liquid fuel dispenser nozzle spouts and a system for differentiating between nozzles that dispense liquid fuel into vehicles with spark ignition (SI) engines and compression ignition (CI) engines for land vehicles. Current legal definitions only distinguish between “Unleaded Fuel” and “All Other Types of Fuel.” These definitions are no longer valid. This document establishes a new set of definitions that have practical application to current automobile liquid fuel inlets and liquid fuel dispenser nozzle spouts.

This test method is intended for measuring fuel permeation at elevated temperature through low permeating hose or tubing samples of elastomeric or composite construction. The expected accuracy of the method is about ±10% of the sample permeation rate. Hose permeation testing can be done two ways: Method A – Plug and Fill or Method B – using a fuel reservoir. Method A involves plugging one end of the hose, filling the sample to about 90% full with test fuel, plugging the other end, and then exposing the plugged sample to a desired test temperature, with the weight loss measured over time. Method B involves plugging one end of a hose, and then connecting the other end to a fuel reservoir. The hose sample and reservoir are then exposed to a desired test temperature with the weight loss measured over time. This procedure presents a recommended plug design that permits inserting the plugs prior to adding the test fluid.

This test standard covers the procedure for measuring the permeation of fuel or fuel surrogates through test samples of elastomeric, plastic or composite materials, up to about 3 mm thick. The method involves filling a test cup with the test fluid (fuel or fuel surrogate), sealing test sample over the open end of the cup, and then placing the sealed container into an oven at the desired test temperature and measuring the weight loss over time. Permeation rates are calculated from the rate of weight loss and the exposed area of the test sample. Standard permeation test temperatures are 40 °C and 60 °C. Standard test fluids are Fuel C, Fuel CE10 and Fuel CM15. Other fluids, such as Fuel CMTBE15, and other volatile liquids may be tested according to this procedure as desired (SAE J1681). The method is not applicable for measuring permeation of higher boiling materials that will not completely evaporate from the exterior surface of the sample at the test temperature.

This SAE Recommended Practice presents standardized test methods developed for use in testing with hydrocarbon fuels or their surrogates and those same fuels when blended with oxygenated fuel additives. Hydrocarbon fuels include Gasoline and Diesel fuel or their surrogates described in SAE J1681. Oxygenated additives include Ethanol, Methanol Methyl Tertiary Butyl Ether (MTBE) and Fatty Acid Methyl Esters (FAME or Biodiesel).

This recommended practice provides a method for establishing the rated or advertised fuel capacity for a vehicle utilizing liquid fuel at atmospheric pressure. It applies to passenger cars, multi-purpose passenger vehicles and light duty trucks (10 000 lb (4536 kg) maximum GVW), (Ref. SAE J1100). It also includes a standardized procedure for creating a full tank when another test requires that condition as a starting point. It is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.

This SAE Recommended Practice was developed to standardize fuel inlet closure colors and verbiage by fuel type primarily for passenger car and truck applications, but it can be applied to marine, industrial, lawn and garden, and other similar applications. See Section 4, Table 1 for a list of specified colors, and text by fuel type.

This SAE Standard presents the minimum requirements for nonmetallic tubing with one or more layers manufactured for use as liquid-carrying or vapor-carrying component in fuel systems for gasoline, or alcohol blends with gasoline. Requirements in this document also apply to monowall tubing (one layer construction). When the construction has one or more layers of polymer-based compounds in the wall, the multilayer constructions are primarily for the purpose of improvement in permeation resistance to hydrocarbons found in various fuels. The tube construction can have a straight-wall configuration, a wall that is convoluted or corrugated, or a combination of each. It may have an innermost layer with improved electrical conductivity for use where such a characteristic is desired. The improved electrical conductivity can apply to the entire wall construction, if the tubing is a monowall. (For elastomeric based MLT constructions, refer to SAE J30 and SAE J2405).
